Aspid GT-21 Invictus revealed – sort of

Aspid – the Spanish supercar maker which was IFR Aspid – has revealed the first images, and video, of the new Aspid GT-21 Invictus. IFR Aspid made the Caterham-esque – and rather bonkers – Aspid SuperSport, but after a change of name to just ‘Aspid’ they teased a new car back in May, which looked to be more mainstream. That tease arrives as the Aspid GT-21 Invictus, which takes the starting point of the very ‘open’ SuperSport and clothes it in a new body that turns it in to more of a GT car – even if it still gets open front wheels.

Olympian Hoy dreams of racing at Le Mans

SIR CHRIS HOY is planning a competitive comeback in 2016, with the Le Mans 24 hours race the target rather than the Rio de Janeiro Olympic Games. The 38-year-old is Britain's most decorated Olympian with six gold medals, including two at London 2012, and has won 11 world titles. He announced his retirement in April 2013, but his passion for motor racing and competition will be fulfilled after agreeing a deal with Nissan, which will see him compete in the 2014 British GT Championship.
